Women's History Month: Rosalind Franklin

VOAVideo: Franklin's Research Led to the Discovery of DNA Structure

Many people have never heard of British scientist Rosalind Franklin. Her research helped solve the mystery of the structure of DNA - the building blocks of life. In 1952, Franklin took X-Ray photographs of a molecule that showed DNA contains two strands wrapped around each other in a double helix, like a twisted ladder. The clearest image, known as photograph 51, enabled other scientists to build a model of DNA, and they received credit for it. In Washington, a play at the Jewish Community Center called "Photograph 51" depicts Franklin as the only woman doing DNA research then in a man's world. The play coincides with women's history month in the US. VOA's Deborah Block has more.
